Solution

The correct option is A $7 x y (2 + 5 y)$
Given, the expression $14 x y + 35 x y^{2}$ can be written as,
$14 x y + 35 x y^{2}$
= $2 \times 7 \times x \times y$ + $5 \times 7 \times x \times y \times y$
= $2 \times 7 x y$ + $5 y \times 7 x y$
= $7 x y (2 + 5 y)$

The correct option is A $7 x y (2 + 5 y)$
Given, the expression $14 x y + 35 x y^{2}$ can be written as,
$14 x y + 35 x y^{2}$
= $2 \times 7 \times x \times y$ + $5 \times 7 \times x \times y \times y$
= $2 \times 7 x y$ + $5 y \times 7 x y$
= $7 x y (2 + 5 y)$
